"Chris was professional and time efficient in the job of installing my new mailbox. I would recommend him as a very good worker and friendly personality. Thanks Carolyn Herrington"

"I 100% recommend Parish Cooling and Heating! Jen and Johnny are the best, and so friendly, honest, and knowledgeable. They went out of their way to ensure I had a new working furnace and coil by the end of the day, despite some setbacks (not on them) and having to work in the sweltering attic. Their prices are actually reasonable too! I didn't feel taken advantage of at all, which is refreshing. I'll definitely be calling them again with any HVAC needs."

"I am totally happy with the installation of my slider door. The tech (Tommy) was very thorough and took his time to get it right. I highly recommend Barrier windows."
